I've also written a short pictorial explanation of mitosis,
and another on telomeres. if you know what i'm talking about,
you'll be bored to tears. if you don't, you might find them
informative.

You may find that some of these images are very dim
on your monitor. You may need to fiddle with the brightness
and contrast to see things clearly.
